I read Intel's connected logistics solution here : [https://www.honeywellaidc.com/solutions/workflow/connected-freight-solution] and reading further into it, I got to know that they were using SimpleLink Bluetooth Low Energy MCUs : [http://www.ti.com/ww/en/wireless_connectivity/sensortag2015/index.html]
My query is whether the sensor data transmitted by these smart tags which are inside metal container of the truck can reach the IoT gateway which is on the driver's panel which is the front part of the truck.
There will be a metal obstacle between MCU and Gateway, so is it possible that Sub-1 GHz or any other feature of the SimpleLink MCUs can aid in transmitting between these two devices ?
